Mahjong power

1. blockchain is a public account book. You can't say that your natural gas and chopsticks violate the law, because they are just tools
Chinese Mahjong: the world's earliest blockchain project
first of all, a initiates an application. I want to play mahjong and set up a mahjong Bureau, which is equivalent to creating a block, and this block will be broadcast to B, C, D, a, B, C, C, C, C, C, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D D...
in the process of playing mahjong, the above four people constantly play cards, which can be understood as mining, through what to mine? Mahjong machine can understand the mineralization machine. These four miners are the so-called miners. These four miners collide from 144 mahjong, and any right card can be Hu card. We can understand the 144 mahjong as a series of hash values (numbers). The process of Hu card is called computational power. Until Hu card, it means that the right hash value is collided and you can get a reward, Each person will pay the corresponding chips to C and put them in the blockchain. The reward is bitcoin or other virtual coins
Why do the other three people take the initiative to reward C? That's because these people have automatically reached a consensus that C has indeed won, and everyone has recorded the account, including the family members who are sitting next to buy horses. It's not good to deny it, otherwise when it comes out that the character is not good, no one will play with him again. After all, the circle is very important
when we reached a consensus, we didn't see any intermediary or third party judging that C had won, and the rewards given to C didn't need to be transferred to C through the third party. All of them were direct point-to-point transactions. This process was decentralization. The card players (miners) recorded their own achievements in the first game, and the third team won the first game, After the record is completed, a complete block is generated. But remember, this is only the first round. In the whole blockchain, this is just a node. The first eight rounds are finished, that is, eight nodes (blocks). Eight blocks are connected together to form a complete account book, which is the blockchain. Because everyone has one account book, it is a distributed account book. The purpose is to prevent someone from tampering with records. In the end, it is clear who wins or loses.

2. Blockchain is an important concept of bitcoin. In essence, it is a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
both eurocrowdfunding and Ethereum use blockchain technology.

Artificial intelligence will replace some people at work. Based on the "five second rule", Li Kaifu predicts that in the next 10 years, about 90% of translation, news reporting, assistant, security, sales, customer service, trading, accounting, driver, housekeeping and other jobs will be completely or partially replaced by artificial intelligence. At the same time, he also believes that most of the work will be transformed into a new form of work

Based on a rough estimate of human work, Li Kaifu predicted that about 50% of human work will be affected by artificial intelligence. So how should the people who are in these easily replaced instries deal with it“ We should think deeply, cross the field, and know what the limitation of AI is. " Li Kaifu said that artificial intelligence is a system of objective judgment based on big data in a single field, so what people need to do is to think more deeply in the strategic and cross domain direction

but artificial intelligence is created by human beings and will not be the overlord

1. Recognize the importance of numbers "in the business world, numbers are very important." This sentence seems abstract, but it is very true. Numbers are like medical checklists, which are the results of actions and tools for evaluation; Numbers are also like dashboards, which can guide the direction and predict the future

The number is an important basis for communication, persuasion and negotiation. For example, if you want to apply for additional equipment, try adding "how much money can be saved in the total cost", and let the number speak for you, maybe you can improve the probability of passing

When evaluating or analyzing any situation, try to digitize it. Simple and clear figures are very helpful to record, convey information, compare, review and analyze business behaviors. It's like learning to be a person who "values the amount of money". Everything is not judged by feelings (feelings, impressions, good and evil), but by "amount", "number" and "ratio"

for example, if you think that holding promotional activities can enhance the popularity of procts, try to convert the popularity into "amount"

When PDC cycle is applied to work, before any action is taken, plan should be drawn up, then do should be carried out, and then check the gap between the result and the plan as a reference for corrective action

When faced with complex problems, we can use the matrix diagram to explore the undetected problems, and then develop countermeasures according to the urgency and importance of the problems

With the concept of time, it is assumed that company a can handle 1 unit of workload in one hour, while company B can handle 10 units in one hour. This 10 times difference can be converted into the workload of company B in one year, and company a will take 10 years. Time can be converted into money, efficiency and speed. Therefore, people with digital power will not waste their time, but also be punctual and trustworthy

Effective use of funds to play the value of money, it must be before the use of money, forecast the effect or benefit, after the use of more detailed confirmation. In daily life, all things must be considered in the way of "profit and loss calculation"

Develop the habit of calculating (total value), many people have similar experience, that is, the wrong number is often like a snowball, the registration of purchase quantity, sales volume or inventory quantity, sometimes if an item goes wrong, it will go wrong all the time. Therefore, for figures or amounts in the chart, it is customary to add them up, which is convenient for us to determine the priority according to the degree of importance in the overall control

9. Digitize all the goals. Carlos Ghosn, CEO of Nissan, once said, "I can't implement goals that can't be digitized."

sometimes, the vision or task of an organization is more abstract, so it needs to be implemented into specific figures to implement and evaluate. For example, the goal of "expanding contacts" can be transformed into "exchange 30 business cards with people every month and keep in touch with 5 of them in the future", or "strengthen advertising activities" can be transformed into "publicize to 15 media and reach 8 real publications"

if the goal is more ambitious, it is better to divide it into three stages: short range, medium range and long range, and then decide the goal to be achieved in each period. This process is the so-called "backward calculation", that is, in order to achieve the long-range goal, to calculate back what should be done in the medium and short range, or even what should be done in the near this month, this week or now, as the check point to achieve the goal

In ancient Chinese thought, 3 is the cardinal number and 9 is the extreme number. In addition to 5 and 3, 9, 12 also plays an important role in ancient culture. In our life, in addition to the five elements, five flavors, five zang organs, five colors and other materials related to 5, there are also many materials related to 12, such as 12 zodiac, 12 hour, 12 hour, 12 hour 12 months...

this idea has been fully reflected in mahjong, 144 is the square of 12, 108 is also a multiple of 12. In addition, in the rules of mahjong, it is stipulated that each player plays 13 cards, and 13 times 4 equals 52, which coincides with the rule of 52 weeks in a year. It reflects the existing form of matter, while numbers represent the quantity of matter

a data feature in the process of calculation, represented by binary digits (zero and one). The expression depends on the relationship between it and some special numbers. Such as... 16, 8, 4, 2, 1, etc

The binary expression of 9 is 1001. Because it has an 8 and a 1

5. Changchun Mahjongg light bar calculate dark bar calculate power door, this you have to see the requirements at that time.

6. Why refute it? In fact, blockchain is very complex. Those who specialize in technology development understand that in their eyes, it doesn't matter what blockchain is, but it's important to make money. Therefore, it's OK to know that people don't take this analogy seriously and don't know that people make fun of it.

7. In fact, mahjong is 3 points and 7 points. In my opinion, if the skill reaches a certain level, playing mahjong will not have a long-term victory over the general.
about skills:
1.147258 rule: if you lose 10000, you will not eat 30000, 40000 or 70000, and you may eat 20000 or 50000

2

3. It's better not to move the card because it's not easy to play. If you want to play a familiar card, it's possible to play a big card

4. If you lose 30000 or 80000, you may hold 30000, 50000, 60000 or 80000 in your hand, and you should be careful when you hit 40000 or 70000

5. If you lose 80000 or 90000, you may still have 40000 or 70000 in your hand. You should be careful when you hit 40000 or 70000

6. In the first few laps, it's better not to eat the two ends of the card except the inlay card and the side card, but to play the other cards first, and then he will play it down when he gets the card at home

7. If you have one card in your hand, if you lose 30000 to this type of card, don't eat it if you have any mixed cards (except for one card)

8. Except for the east wind, all the wind is out there, so we can't fight. We may have to open the bar, at least watch two laps before fighting

9. 70000 people have been touched outside, 80000 people have seen two, 90000 people have been touched basically

10. At the beginning of the card, lose one card first, and then lose Fengzi, but no more than two Fengzi in hand

11. If you eat 2, 5 or 8, you don't need to eat them

12. Don't lift a piece that you haven't seen before. It's better to lift both ends of the piece and see a piece of Zhang or Fengzi outside

13. In the first few laps, if someone throws the east wind and the west wind in his hand, he should throw the west wind first, because someone may take the west wind and others will throw you out of the circle, and you may get the east wind right

generally speaking, after playing a card, it's not a wind arrow, and there's no nine. You can see the middle card or the side card, which indicates that the card game is better
or the design is not reliable. When the other three play, you should be more careful

for the playing method of mojiuxianzhang, there are the following situations:

(1) for the card makers who design "clear", "mixed" and "missing one door", they should first get rid of the unnecessary categories of
mojiuxianzhang

(2) in a card game, the existing deck, tie or pair are all made up of middle cards, so when designing a card game, we must consider the possibility of "breaking the" card, no matter which one or nine cards can be knocked out; If there are many matchups and pairs in the card game,
is ready to rely on eating, touching and catching to form a pair, and consider leaving a piece of Yao or Jiu that has not been met as a single fishing bid, the success and hope will be greater

therefore, in this case, it depends on the development of the card game

(3) if there are l, 2, 3 or 7, 8, 9 shunzi pairs in the deck, then when you play Mo and Jiu Xianzhang again, you should weigh them against the "average height" and "sister flower" designed by
to decide whether to play or stay? The priority should be considered as a whole

(4) in the later stage of the card composition, on the basis of the original side cards 8 and 9, when catching the same kind of cards 6, we should play
9, keep 6, and make 6 and 8 inlays. The same is true for the small head. For example, on the basis of the original side cards L and 2, when catching the same kind of card 4,
should also play "Mo" to leave a 2 or 4 inlay

(5) in addition to the arrow wind, the design thirteen does not depend on the card game. For Wanzi, tiaozi and Tongzi, it is true that they are best to keep and
nine. In the middle, they can be expanded to 4, 5 or 6, and the number of cards can be widened, which is beneficial to the last card. It is true that the nine free cards in
can not be knocked out, but should still be regarded as the best card

once the last one is right, it is the best mahjong head in a good card game. Zhongzhang, like this, is free and useful. Of course,
in xingzhang, it is not easy to give up<

3. There are three players in the view of zhongpanshe card

the stage of zhongpanshe is a stage of fierce and intense battle, and each player is related to the victory or defeat, so each player must really grasp the safety barrier, and try to make sure that the player has no food, no chance for other players, and no possibility for other players to succeed

in Mahjong practice, as long as the card potential enters the middle stage, each family's hand will change all the time. After playing one to two rounds of cards,
the previous familiar card may have become a new card at this time. It used to be considered as a safety card, but now it is likely to become a dangerous card. At this time, if you give up, you will be eaten by the next family, or you will be made up by the rest of the family, It's a long way to go.
old security has changed into new danger

mahjong players should formulate strategies and tactics according to the changes on the card surface and table, so as to look at the home, keep silent and focus on the home

look home. That is to say, we should see what kind of cards we play at home, and what kinds of cards we eat and touch. Because the cards he eats and touches are the colors he needs; The cards you play are also the colors you can eat and touch. In this way, you can judge what kind of suit you should keep so that you can have a chance to eat and touch cards quickly. If
the colors in your hand are what the family wants to keep and don't give up, naturally you can't quickly
combine the cards in your hand by eating and touching cards

keep silent. Instead of looking at the home, the home is trying to rely on your hand to play the card to determine their own hand in the go or stay. If most of the cards you will play are the ones you want to eat, then of course you will eat them quickly and show them out in pairs,
and ask to listen. Therefore, when playing cards, it is very important to try not to make the next family eat the cards they gave up

look at home. You should not only look at the home, but also keep an eye on the other family. In this way, what kind of cards the three families need, and even what kind of cards they may need, are in your expectation. For yourself, you must consider carefully what you want to do, what kind of cards you want to play and what kind of cards are good for you, so that you can succeed at one stroke

4. At the end of the game, you can't be negligent

there are two situations when entering the final game:

one is that two or one of the four people still listen to the cards and watch the game. However, e to the flat development of card potential, we have to
play cards by force and socialize with the war situation. The other teams were defensive and ended up with less points

Second, four people continue to check each other and play the safety card. In fact, one or two of them had already given up listening to the cards and adopted the battle plan of
getting less points

this situation is not uncommon in the competition between all the top players in the card instry, which is quite different from the first hand players who gather at the table for entertainment and push down the food. If there are one or two underhanded players on the card table, it seems impossible for the war to reach the final stage

the following is about how to deal with several kinds of cards:

① shooting danger card

the danger card here refers to the absolute danger card that makes his family harmonious after it is released. When the card game enters the middle stage, it is full of many dangers for any house

in fact, some cards are not dangerous cards in many occasions, but feel that they are not safe cards, which is caused by the influence of the concept of shooting

therefore, ring this period, each card can not be a safety card for the other family, so how to deal with these dangerous cards
needs further discussion. In addition to the absolute safety card (for example, if the character card comes out of the East and touches the fourth card), other
cards are always a little dangerous. Now focus on the danger card of shooting and observe the change of that point

First: the shooting danger card refers to the card that the opponent wants after listening to the card. Once it appears, it can become a sum. If there is a certain card in the hand
now, which is not the danger card of direct shooting, but because this card is touched by the other party and causes him to complete a large number of listening
cards, then this card should be regarded as the danger card of shooting

Second: if you can see the situation of the opponent's FanTai in the late middle game, then all kinds of cards that have nothing to do with FanTai can be counted as safety cards

thirdly, the risk of shooting can sometimes be inferred from the way of each house's card phase. The card with less types of houses is more dangerous, especially the card with more risks

Fourth: the dark ridge in one's hand and the card on the same line are dangerous cards for shooting. For example, there are 3
and 6
cards in the hand. When there is no such card on the table, someone may listen to 3 or 6
calls, and half of his and his calls are in your hands, which can greatly prevent others from winning

② the abandonment method of high danger card

knowing that it is a shooting card, no one will play outside. However, in the case of suspicious high-risk cards, it depends on the player's courage and his expectation of the winning or losing of the card. From the late middle set stage to the final set stage, for example,
when one's own hand is not likely to form multiple card positions, and the other's hand is full of multiple shape omens, it's better to die,
don't play dangerous cards, or even remove face safety cards, so as to get through the difficulty of playing cards in the last one or two rounds until the yellow card<

③ the processing method of shooting card

the first is to incorporate the combined face. At the end of the game, since the shooting card can't be played, it can't be left alone in the hand
card to hinder yourself and the card. In this way, it's better to put the shooting danger card into the hand card, which is the safest and
the most favorable method. Because in this way, the left and right contact cards of this shooting danger card are also marked with insurance coefficient,
will not be easily given up, so that the risk is greatly reced

Second: quit the winning and losing circle immediately. In Mahjong competition, it is very wise to withdraw from the winning and losing circle immediately. In particular, the posture of many players who listen to the cards clearly knows how to touch the dangerous cards, but they are afraid that they will disturb the formed card potential, but they insist on giving up, hoping to get away with it. But I don't know that such a strategy will win or lose. There is no saying that shooting and passing can be done in five or five ways< Third, there is no security card. In all kinds of cards, people often feel embarrassed that there is no safe card in their hand. It is true that this is man-made, which can be divided into two types: first, there are too many friends in the hand,
and they are greedy to eat when they eat and touch when they have to. They have neither calculation nor strategy. As a result, the hand
is relatively reced, the room for maneuver is narrowed, and the adjustment area is narrowed. There are only a few cards on hand, that is, there is no safety card to play, which brings great confusion and even the risk of shooting. Second, although the front door was clear without eating and touching, the hand was 13

The first stage is artificial intelligence assistant stage. That is to say, at present, AI benefiting the people is not necessarily challenging the limits of technology, nor trying to replace human beings. In fact, in many instries, the application and popularity of artificial intelligence technology is very low, and the space for simple upgrade is very large

The second stage is dominated by AI. A large number of specific work transition to robot and virtual human based. The role of human has changed from direct work to indirect command and control of robot. Under the pressure of market competition, artificial intelligence will sweep the human society: a securities company using robot operators will urge all securities companies to use robot operators; If a hospital uses robot doctors, it will encourage all hospitals to use robot doctors; Using robot soldiers in one country will encourage all countries to use robot soldiers

The third stage is the replacement stage of artificial intelligence. Artificial intelligence can replace human beings in scientific research and innovation, and "artificial consciousness" technology has made a breakthrough. At this time, people no longer need to worry about the ability of artificial intelligence, but began to worry about the role of human beings

The essence of the world is calculation, the essence of society is calculation, and computers are just not lacking. In an era when computers can accomplish everything, human work and study are no longer just needed. Human beings can already look forward to the Great Harmony of the world brought about by the high development of artificial intelligence, except for the fear of how to exist if the value of human to the world is only species diversity

it is necessary to start thinking about the role of human beings in the post AI era now. Instead of coming back to solve problems in the future, we should take precautions now. Artificial intelligence is bound to benefit all mankind and threaten all mankind as a whole. If the world is allowed to choose for itself, will it also tend to be more green and intelligent "new humans"? We may be able to set some red lines for the development of artificial intelligence technology, but how can we ensure that there will be no overstepping? We may be able to integrate human beings with artificial intelligence, not only to create robots, but also to transform people themselves, so as to carry out "artificial intelligence +" to the end. In a word, if we can't solve the double-edged sword problem of AI development, we are on the way to hell
